[Lapack] widespread failures in dgd.out

Guys,
If I build lapack 3.3.1 or 3.4.0 from the tarfiles (with f77blas), and then
do a "make double" in TESTING/, then when I scope dgd.out I see:
DXV drivers: 200 out of 5000 tests failed to pass the threshold
When I look at these errors, many are of size 10^3, which often doesn't mean
error at all, but quite a few are more like 10^7, which usually indicates
a real error.
Is this behavior expected and what is the explanation?
Many thanks,
Clint
